Field of the Invention The present invention relates to a disk (a disk-shaped workpiece) which is a storage medium of a hard disk drive (HDD) and is made of a hard brittle material such as glass or ceramic. Peripheral processing device. [Prior Art] In order to achieve high storage density and stable high-speed rotation, it is required that the surface and the back surface of the disc as the storage surface of the Gongxun have extremely high surface precision, and the processing of the outer peripheral portion of the disc must also require machining accuracy. . In the past, the surface and back of the disc were processed by two grinding processes (lapping) and fine grinding (polishing_gangming), and the outer circumference of the disc was machined by peripheral grinding and chamfering. . In general, the processing sequence is 'after grinding the surface and back grinding, and then grinding and chamfering the outer peripheral portion, and then performing the second grinding and finishing grinding on the front and back surfaces. Referring to Fig. 12, the chamfering process of the outer peripheral angle of the disk-shaped workpiece (the disc}: the ridge line between the surface and the outer peripheral surface) is performed by the grinding wheel 6. = force: the workpiece 1 level The rotating workpiece held in the wrong direction is rotated about the axis of the workpiece shaft 11, and the grinding wheel 6 mounted on the rotating grinding wheel shaft 61 of the workpiece 2 is rotated, and the workpiece 1 is machined. In the trapezoidal groove 65 formed by the outer peripheral surface of the grinding wheel 6, the upper outer peripheral angle and the outer peripheral angle of the lower and lower sides of the grinding wheel are simultaneously performed (4). In this case, the '凊 fit is shown in ® 13 and the sand is The direction of sliding friction of 4 is the direction of the line 16 of the chamfered surface of the piece 1 which is indicated by the arrow d, and is chamfered in the prior art; the workpiece is called the table, and the chamfered surface 16 of the piece of the workpiece is 16 The inter-angle (ridge line) 18 will produce a micron-sized fragment of 201134609. The state PP_7 debris must be removed by the second grinding described above. In order to ask the productivity of the workpiece 1 and reduce the production cost, it is expected to be reduced. Work: 1 plus n order 'for example: reduce the grinding and grinding to the - process. If you can omit the second The secondary grinding process and the finishing grinding immediately after the chamfering process can greatly reduce the processing steps of the work. Moreover, the prior art grinding wheel 6 must simultaneously face the upper and lower circumferences of the workpiece. Processing, so there is a problem of large processing load 'and... must be a high-hardness grinding wheel that is electrodeposited on a gold 4 substrate by a diamond abrasive, and when the grinding wheel 6 is worn, it is necessary to replace the second wheel 6 in time. The present invention has been made to solve the aforementioned problems, which can prevent the chamfering of the chamfered surface 16 of the workpiece 1 and the angle 18 between the front and back surfaces 17, thereby eliminating the second grinding after chamfering. Machining, and the processing load of the chamfering grinding wheels 3a, 3b is small, changing the field 丨, * member J & general grinding wheel combined with ordinary abrasive: can be adjusted by (four) angle grinding wheel 3a, 3b and workpiece, The relative position of the month b allows the workpiece 1 to maintain the surface accuracy of the processing and the machining shape of the grinding wheel without frequent replacement of the chamfer.
